TELL CITY, rumana TIRE.

`pplicatikon led June 3,

The object of this invention is the provinfiuenced tire for automosionv of a spr' l biles or like lxiilicles, which will afford the all wheel on which itis arranged a resiliency at least equal to that of a pneumatic tire and `which overcomes all the undesirable fea-tunes of the latter type of tires, inasmuch as the salue is puncture-proof, needs no adjustment after being arranged ou the wheel, is exceedingly long lived and which exerts practically the same tension throughout the circumference of the tire. i

To the attainment of the foregoing the invention consists in the improvement as hereinafter described and definitely claimed.

In the drawings:

Figure l is an approximately central longitudinal sectional view through a spring tire in accordance With this invention.

Figure 2 is a sectional view approximately on the line 2-2 of Figure 1.

Figure 3 is a sectional view approximately on the line 3-3 of Figure 2.

Figure 4 is a sectional view approximately on the line 4--4 of Figure 2.

`The hollow body of the tire is preferably made up of sections to include an inner cylindrical ring 1 that is arranged over and fixed to the felly` of a wheel. he inner member 1 of the tire has its edges provided with outwardly directed continuous flanges 2 and to these flanges there are secured by Ybolts or like removable means 4f, the sides of the tire. Between the sides 5 there are secured by removable means 6, the flanged edges of spaced cylindrical ring members 7 and 8, respectively. The members 7 and 8 provide spacer' plates for the sides and also materially reinforce the sides7 but in addition to this the members 7 and 8 are provided with equidistantly spaced round aligning openings through which are guided tubular members or plungers 9. These plungers have their inner ends provided with reduced cross sectionally rounded stems 10 that are received in sockets V11 which are `preferably revolubly connected with the inner or base member l of the tire. Surrounding the sockets 11 and the stems 1() and exerting a. pressure between the plungers 9 and the base 1 of the tire there are coil springs 12. On the outer end of the plung- V ers 9 there are fixed arcuate plates 18. By

reference to Figure 3 of the drawings it will be seen that the plungers are arranged `in opposite circumferential series and that 1927; serial No. 196,330.

the plungers of' one series are arranged in staggered relation with respect to the plungers of the second ser-ies, that is the plungers of one series are disposed approximately centrally between the plungers 'of `the second series. The plates 13 are arranged end to end but are out of contact with each other. The plates have end and edge as well as central outwardly extending impinging elements 14, that enter tl e solid rubber tread 1,5 of the tire. The sides of the tread are vreceived between the side plates of the tire, and the plates 13 have their outer edges formed with lugs yor projections 16` that are received in guide notches 17 on theinner faces of the side members 5 of the tire. The lugs contacting with the end walls of the not-ches limit the outward movement of the treacL 15 through. the influence ofthe springs 12 and likewise limit the inward Vmovement of such tread.

The simplicity of my construction and the advantages thereof will, itis thought, be understood and appreciated by those skilled in the art to which the invention relates after the foregoing description has been carefully read in connection with the accompanying drawings but it is thought necessary to add that I do not wish to be restricted to the precise construction and details herein set forth and therefore hold myself entitled to such changes therefrom as fairly fall y'ithin the scope of what I claim.

Having described the invention, I claim l. A tire for vehicle wheels, comprising a body member which is substantially U- shaped in cross section and which has outwardly extending sockets, transverse members connected to and bracing the sides of the tire, plunger membersarranged in opposite staggeredly related series guided through said brace members, stems on the plungers received in the sockets, coil springs surrounding the sockets and urging the plungers in an outward directiomsegmental plates fixed on the outer ends of the plungers, coengaging means between said plates and the inner sides of the tire for limiting the movement of the plates in both dir ctions with respect to the tirefand a solid rubber tread having its sides received between the sides of the tire and secured on said plates. Y

2. A tire for vehicle wheels comprising a cylindrical base ring having its edges flanged outwardly, flat annular side members bolted to the flanges of the base, cylndricgrl spacing and bracing rings for the sides removably secured thereto, plunger-s arranged in opposite and staggeredly related series guided through the last mentioned members und having inwardly projecting stems, swiveled sockets on the base of the tire in which the stems are received, eoil springs surrounding the sockets and exerting a pressure between the base of the tire and the plungers, segmental plates fixed on the outer ends ot' the plungers, and having outwardly projeetingr lugs, the sides of the tire having guide grooves for the lugs, impinging elements on the segmental plates :uid :1 solid trend ur- Yranged over said plates, receiving the i111- pinging elements therein and guided be tween the sides of the tire.

In testimony whereof I affix my signature.

JOHN SCHRANER.
